【Product Description】 This is a blue Proportional Chair with an auxiliary cushion from Miyatake Seisakusho. Do you ever wonder if your child lacks concentration when you see them studying, but they're distracted or not making much progress? The Proportional Chair(R) can help improve concentration just by sitting in it. *The effects have been proven in experiments conducted by the Faculty of Engineering, Kagawa University.* The slanted seat allows the pelvis to stand like a standing posture, naturally creating an S-curve in the back and producing an ideal posture. Also, sitting in the correct posture helps maintain a proper viewing distance. With height adjustment and an auxiliary cushion, it can be used by children from 110cm tall. I purchased this new from an online shopping site a year ago, and my child was using it. I am selling it because my child no longer uses it after receiving another posture correction chair from their parents. There are small scratches and scuffs on the frame, but the cushion on the seat is in good condition without any sagging. The sticker is peeling off. Please check images 4 and 5. There is some fuzzing on the cushion of the knee rest where the auxiliary cushion was placed (due to the Velcro). The Velcro on the auxiliary cushion is weak and doesn't stick, but it was still usable without the cushion slipping. Please refer to the photos to assess the condition. ・Please purchase if you understand that this is a used item. ・Everything in the photos is included. It will be shipped assembled.
